Abstract (en)
The disclose technology includes methods, systems and related aspects for establishing a wireless communication channel between a broadcaster and an observer. The method comprises configuring a plurality of global broadcast parameters using an out-of-band communication channel and using at least one of the plurality of global broadcast parameters to form a broadcast unique identifier code for a network advertising broadcast. The global broadcast parameters include at least one synchronization value and one or more global parameters based on the capabilities of both the broadcaster and the observer comprising: a minimum network advertising broadcast interval between sequential network advertising broadcasts, a minimum network advertising broadcast synchronization, MinNABS offset comprising a minimum interval between transmission of a synchronization value and the network advertising broadcast, and a maximum network advertising broadcast synchronization, MaxNABS, offset comprising a maximum validity time-period for a synchronization value. In this way, replay attacks which spoof the broadcaster may be prevented.
